Measuring and Observing of Ambient Temperature of Broiler Chicken Farm at Gianyar Region by SMS Based AVR Atmega16 Microcontroller

Abstract This article designs a measurement tool and an ambient temperature monitor of Broiler chicken farm at Gianyar region by applying LM35 temperature sensor as temperature detector, ATmega16 Microcontroller is functioned as the main control of the system and SIM 800L Module is functioned as SMS sender and receiver. Optimal ambient temperature of broiler chicken farm is between 16 0C till 26 0C [7]. The made tool will report the temperature of broiler chicken cage automatically through SMS massage if the cage temperature is less or more than optimal temperature limits. The monitoring is also done every second by sending SMS massage “Lapor” to the hand phone number that has been installed on SIM 800L module and the tool made to reply the massage is temperature report to the sender. Calibration result of sensor LM35 done at BBMKG region III Denpasar said that the uncertainty of measurements is avowed at confidence level that is not less than 95 %. Experiment result of the test equipment on broiler chicken farm at Gianyar region monitored by SMS for 4 days showed that average ambient temperature of broiler chicken cage was 28,22 0C.
